I was flying last evening with another fellow and noticed an elevation issue. He was using FSX Steam and I was using P3dV3.4. We were at Hood River, Or, airport on the ground. When I was on the ground he was about 6 feet in the air. We also experienced this issue a couple days ago at Port Hardy.

We have been suffering, or rather, experiencing, the same thing. We are a mixture of P3D and FSX and have differences in elevation of the sort only seen before when someone doesn't have a particular piece of scenery installed. Last Saturday and the previous Saturday we saw this even though we all had the relevant airports. Could this be due to the elevation corrections feature? The terrain on these airports was undulating (outback Australia)

Speaking for myself, all the wayward aircraft were higher than me. I didn't see any 'shark attack' instances. There were 5 P3Ders and 3 FSXers. If we have any more roller coaster runways I'll take a survey of who sees what. But it won't be until next Saturday.
